Forensic wound age estimation in dog tissue correlated with newly formed collagen fibres: a retrospective study.

Parameters for wound age estimation are essential in forensic pathology but difficult to assess. With this retrospective study, wound age parameters in canine skin wounds were assessed with archive material of known age. Haematoxylin and eosin (HE) staining as standard, Prussian blue, Van Gieson (VG) and multiple other special stains were used as well as various immunohistochemistry (IHC) tests.

Frequent Occurrence of Simultaneous Infection with Multiple Rotaviruses in Swiss Pigs.

Rotavirus (RV) infections are the most important viral cause of diarrhea in piglets in Switzerland and are thought to cause substantial economic losses to the pig industry. However, no data are available on the occurrence and dynamics of the main porcine RV species, namely RVA, RVB, and RVC, and the diversity of the circulating strains. We therefore tested fecal samples from a cross-sectional ( = 95) and a longitudinal ( = 48) study for RVA, RVB, and RVC by real-time RT-PCR and compared the results of the cross-sectional study to postmortem findings.

-Induced Arthritis in Experimentally and Naturally Infected Sheep.

is an obligate intracellular pathogen with a wide host range including livestock such as sheep, cattle, goats, and pigs as well as wildlife species such as koalas. Chlamydial polyarthritis is an economically important disease resulting in swollen joints, lameness, stiffness, and weight loss in young sheep. In the present study, tissues from sheep experimentally or naturally infected with were assessed by histopathology and immunohistochemistry.

Endocardial fibroelastosis in a dog with congestive heart failure.

In a 6-month-old, intact female, Japanese spitz presenting with severe dyspnea, lung ultrasonography revealed confluent B lines associated with severe echocardiographic left sided volume overload and systolic dysfunction. A congenital shunt or valvular dysplasia was not demonstrable. On electrocardiogram, there was a constant sinus rhythm, respectively sinus tachycardia.

Porcine Circovirus Type 2 Pathogenicity Alters Host's Central Tolerance for Propagation.

Porcine circovirus type 2 (PCV2) infections and resulting diseases are a worldwide threat to pig production. PCV2 bears a uniqueness that allows for us to understand more about chronic infections and the immune system in general. The virus can be phylogenetically subdivided into PCV2a to PCV2h genotypes.
